pressbooks-6 Degraded performance on pressbooks-6

High throughput distributed brute-force login attempts caused markedly slow response times during 13:14–14:29 UTC. Firewall tightened within minutes of onset, tuned over time. Slightly slow response times continued until 16:35 UTC, then returned to normal. Experienced slow response times again 19:31–20:03 UTC, but then our actions restored normal response times.
